Work has begun on on Six Sigma’s upcoming condo at 435 West 19th Street, and the head-to-toe renovation/addition of the 1924 building seems intent on housing all the most outrageous frills of recent West Chelsea builds under a single roof.

Boutique design-and-build firm Six Sigma acquired the 20,000-square-foot office building, once home to the photography studios and sound-stages of CityStage, for $21 million in August 2014. According to the developer’s website, Pei Partnership, a firm founded by the sons of renowned Chinese architect I.M. Pei, is crafting the design. Pei Partnership, not to be confused with Pei Cobb Freed & Partners, was also the designers of The Centurion, the Midtown condo lavishly clad in a cascade of Burgundy limestone.
